Ok...thanks. another question. Does it matter where the gryo unit is placed. I ask this because when testing to see if the wheels stay in place, they don't really move as I.have.seenin a number of setup videos.

to get best results place the gyro as close to the center as possible on the chassis this will give you the best resolution from the gyro and servo because thats were the cars center point pivots round just like a helicopter pivots round its main shaft
